excellent job. with the yellow zip ties it blends right in.
did you make that bracket? Looks perfect. rep given.
I really like the way that fan tucked under the bracket. Looks pro stock.

Edit: btw very clean build i really like the seasonic power supplies.. after having issues with a few computers that i just couldnt resolve.. I went to seasonic funny i dont even think about it anymore. No issues..Edited by sunset1 - 12/15/12 at 6:40am

Putting shims will reduce performance, any interface between materials will impede heat transfer. You would have to put thermal paste between all of your different layers to reduce the effect but you would never get any benefit from adding layers.

Thanks! One more thing, does that apply to the back of the card for the 2 memories? What if I put a copper block like this on the back?

Even though there is some resistance to heat transfer the heat sinks will improve the heat dissipation because the surface area is much larger than the flat mem chips. Make sure you have a good thermal tape or other heat conducting adhesive. Also consider that those heat sinks will be slightly raised blocking the slot above your card if its not in the top slot. Back plates that you buy for cards serve the same purpose by increasing the area for convection while still keeping the cards "low profile". I don't know how well they work since I have never used one but I don't have a card with memory on the back.
